Abstract：Aiming at the problem that the tracking error of traditional control method is large due to the complex and changeable running environment of heavy haul train,a new discrete integral terminal sliding mode predictive control scheme is proposed.In this scheme,a discrete integral terminal sliding mode control law based on adaptive switching control is designed.In order to improve the tracking accuracy of heavy haul train system,the model predictive control is combined with discrete integral terminal sliding mode control,and the discrete integral terminal sliding mode predictive control scheme is derived.The unknown disturbance and system discretization error of heavy haul train multi-input multi-output system are estimated.The simulation results show that the particle 1 velocity tracking error of the control method proposed in this paper is within±0.2 km/h,and the control force of each particle changes smoothly and is smaller than that of the comparison scheme.
